如何配置gmail smtp和phpmailer？

Question

我想知道问题出在哪里，因为我收到身份验证错误。

我已经有几个 Gmail 帐户，
我为我的网站创建了一个新网站，
我在 "Account and import" 中向我的旧 Gmail 帐户添加了一封新电子邮件。
我将新的电子邮件用户名和密码复制到 phpmailer 代码

include_once('phpmailer/class.phpmailer.php');
include_once('phpmailer/class.smtp.php');
//6nb5Drv;
function sendmail(){
$mail = new PHPMailer();  

$mail->IsSMTP();                                      // set mailer to use SMTP
$mail->SMTPAuth = true;     // turn on SMTP authentication
$mail->SMTPSecure = "tls";
$mail->Host = "smtp.gmail.com";  // specify main and backup server
$mail->Port = 587; // Set the SMTP port i tried and 457
$mail->Username = 'newmail@gmail.com';                // SMTP username
$mail->Password = 'newmailpass';                  // SMTP password

$mail->SMTPDebug  = 1;                     // enables SMTP debug information (for testing)
                                           // 1 = errors and messages
                                           // 2 = messages only

$mail->From = 'from@yahoo.com';
$mail->FromName = 'From';
$mail->AddAddress('to@gmail.com', 'To');  // Add a recipient

$mail->IsHTML(true);                                  // Set email format to HTML

$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <strong>in bold!</strong>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->Send()) {
   echo 'Message could not be sent.';
   echo 'Mailer Error: ' . $mail->ErrorInfo;
   exit;
}

echo 'Message has been sent';
}
sendmail();

但是我收到身份验证错误。怎么了？可能与凭据有关，我该如何配置 gmail smtp？

Answer 1

根据这个post： PHPMailer - SMTP ERROR: Password command failed when send mail from my server，在某些情况下，您必须指定 google 这不是可疑的 activity 并在您的帐户中激活一些 不太安全 的选项。
假设这是正确的密码...
